# [Tex/LaTex] Beamer slides look blurry at lower resolutions

beamerfontspdftex

I prepare slides using Beamer and PDFLaTeX. The command I use to run PDFLaTeX is the default AUCTeX command:

pdflatex  -interaction=nonstopmode "\input" <INPUT_FILE>


The slides look fine on my screen at my default resolution (1360×768), but if I have to step down the resolution (e.g., to 640×480) when I connect to a projector, they look aliased and blurry. Probably this has something to do with the kinds of fonts that are being used, but I don't know how to fix it. Any suggestions?

Or switch to another T1 supporting font like lmodern, which is very similar to the standard font. \usepackage{lmodern} could be sufficient.
